Engaging Data FIRE Calculator
Tap a star to rate
Engaging Data's FIRE calculator combines Monte Carlo analysis with historical stock and bond returns to project your path to financial independence. You input your current savings, monthly contributions, and target yearly spending, then the tool runs thousands of simulations to estimate your most likely retirement age and confidence level. It also shows the range of outcomes, best-case, worst-case, and median scenarios, so you're not blindsided by market volatility.
Best for people who like statistics and want a realistic picture of retirement timing based on actual market history. If you're already deep into the FIRE community and want to stress-test your plan against historical crashes and bull markets, this tool's probabilistic approach beats a simple linear calculator.
